Because even the web has a backend
If I am a strong web believer, from a developer point of view I am not only interested in web development and even looking forward software development very much.
I especially like solving hard problems and making good software, that is to say, good for the users AND the future next developer: Adaptable, flexible, scalable... (don't take me wrong: this issues also happen in Web Dev.!)
I am especially looking at distributed systems and software that interacts with network in order to provide interactive user experience.
From now on, I have mainly been working with C++, Java and C# in this area but I am always interested in learning new technologies.
